It's not just bathroom brands we've assessed - we've also rated power and electric shower brands and tested electric showers in our labs. To find out what genuine customers think about their showers we asked over 3,000 Which? members about the models that they own. This feedback, on major shower manufacturers such as Mira and Triton, has enabled us to give each brand a unique customer score plus star ratings for important factors, such as their showers' build quality and ease of use.

We are also able to reveal results for bathroom installation for Wickes, B&Q and Bathstore, alongside independents. The top company got 77%, while the bottom an unimpressive 51%.
